This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …

In 2019, the largest mechanical flotation cell with a volume of 680 m 3 (500 kW motor power) was installed in Dexing Copper mine (China) with a throughput of 30–100 m 3 /min (Yang et al., 2019). This strategy has been a matter of argument over many years. The present paper points this out by categorizing flotation cells into mainly two ...

Thus in an ore containing both sulphide and oxide copper the recovery credited to the process should be based on the sulphide copper content of the feed, concentrate and tailing, if a true measure of the efficiency of the process is sought. Froth-flotation, properly practiced, will recover from 60 to well over 95 per cent, of the sulphide ...

While the copper mineral is usually in the form of sulfuration exiting in the mineral. Its natural floatability is good, so froth flotation is the main method of extracting copper ore. According to the processing order of the useful mineral, the copper ore processing/mining can be divided into precedence flotation, equivalent flotation, mixed ...

Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as …
